This happened a few months ago.
Rode a gated logging road to the east side of Alouett Lake with Leo. And stayed overnight by the lake. A small creek was joining at the spot, so fresh water was readily available.
On the contrary to the popular west side, this part was very quiet.

The main purpose of the trip was to check out the bike path from Maquabeak Park to Colony Farm, that was closed due to Port Mann construction.
I've found a detour which is not so much of help for commuting cyclists, but may be OK for tourists.
